STL to OBJ STL to OBJ

The OBJ model and its companion material or resource files are kept together in a ZIP package, so nothing required by the model is lost.
Convert an STL triangle mesh to OBJ geometry. STL usually carries no useful material or texture data, so conversion cannot recreate them. Keep any OBJ sidecars with the model; mesh repair is not performed.

Conversion settings

Choose settings before adding files. The same settings apply to the whole batch.

A scale of 1 preserves the original size. Scaling changes the geometry, not the declared measurement units.
